128 If Something Goes Wrong Develop good computing habits ❖ If you have enabled any security provisions (closed system, MAC address filtering, Wired Equivalent Privacy [WEP], etc.), check the access point vendor's Web site for recent firmware upgrades. Problems with WEP keys, in particular, are frequently addressed in new firmware releases. The Windows® operating system wireless management utility does not work. If you are using an external Wi-Fi® adapter (USB adapter, or other variety), check if the adapter comes with its own management utility. If it does, the utility may be disabling the Windows® operating system wireless management utility, in which case you must use the adapter's management utility. If the documentation that accompanies the adapter does not provide enough information to determine if this is the case, contact that vendor's support group for further advice. Develop good computing habits Save your work frequently. You can never predict when your computer will lock, forcing you to close an application and lose unsaved changes. Many software applications build in an automatic backup, but you should not rely solely on this feature. Save your work! See "Computing tips" on page 64 for instructions. On a regular basis, back up the information stored on your internal storage drive. Use Windows® to back up files, or the entire computer, to an optical disc, or external hard disk. Here are some ways you can do this: ❖ Use the Windows® operating system to back up files or your entire computer to an optical disc via an optional external writable optical disc drive or external hard disk. ❖ Copy files to a rewritable external storage device. ❖ Connect your computer to the office network and copy files to your network partition. Some people use a combination of these methods, backing up all files to tape weekly and copying critical files to external media on a daily basis. If you have installed your own applications, you should back up these applications as well as your data files. If something goes wrong that requires you to reformat your internal storage drive and start again, reloading all your applications and data files from a backup source will save time.
